: Low-voltage asynchronous motor is the most common load used in any industrial electric facility. Due to their robustness and reliability, the induction motors have a very large application spectrum and are to be found in a variety of power units. It is assumed that over 70% of total energy used in any electric utility is dedicated to the electric...

The objective of the paper is to present some improvements done on the previously described electric drive elevator prototype [1]. The modern electric elevator contains both the cabin (replaced at the research laboratory by one trolley), and the counterweight (replaced by the opposite trolley which contains modular weights). Through the appropriate...

Present manuscript deals with the biometric identification and security. Features exploited for the purpose are the principal lines of the palm of an individual. We developed an algorithm which extracts palm region from a human hand, calculates few palm specific parameters using only principal lines that differentiate one palm from another and then...

This work focuses on studying signal detection using three different equalization techniques, namely: Zero Forcing (ZF), Minimum Mean Square Error (MMSE) and Beam Forming (BF), for a 4×4 MIMO-system. Results show that ZF equalization is the simplest technique for signal detection, However, Beam Forming (BF) gives better Bit Error Rate (BER) perform...

Nowadays, the use of remote monitoring and transmission of vital parameters became extremely common, because these systems reduce the degree of risk among ill people and provide an additional time necessary for the intervention teams - in case of emergency action. Generally, these devices monitor and transmit data as values of blood pressure and th...

This paper presents the magnetic cardiac stimulation, more precisely the stimulation with an electric field produced by a time-variable magnetic field. The modeling within this domain has in view the investigation of the induced currents in the body and the characteristics of the defibrillation coil (shape, number of turns, length) and the applied ...

This work explores beam forming and two-way relaying to alleviate the dual issues of the spectrum congestion and spectrum under-utilization. These problems can be alleviated by the implementation of underlay cognitive radio networks. However, their reliability, capacity or power, and coverage depend on bi-directional or abbreviated as primary-to-se...

The study aims for the development of a unique positioning system in the world of microscopy consisting of a transducer and software application. The technology used is based on image processing which creates a special hardware (transducer). The virtual labeling is the essential idea of this system. It synchronizes two essential things: the actual ...

The paper presents the main electrical loads that require reactive power, evaluating also its value in different operating states of the industrial installation (permanent sinusoidal or distorted). Also, the effects of reactive power flow in the networks are quantitatively estimated and accordingly, a series of specific power quality indicators (e....
